iphone - 由于未捕获的“NSUnknownKeyException”而终止应用程序，

Question

不断收到此代码的此错误，我使用了它崩溃的断点

GameSelect *selectGame = [[GameSelect alloc] initWithNibName:nil bundle:nil];

我不知道发生了什么我只是从一个笔尖切换到另一个笔尖

- (IBAction)playButtonPressed:(UIButton *)sender {
    GameSelect *selectGame = [[GameSelect alloc] initWithNibName:nil bundle:nil];
    selectGame.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:selectGame animated:YES];
}

Answer 1

your initWithNibName is set to nil. You should put a name for your nib.

Answer 2

尝试将您的 nib 文件名放在这里： GameSelect *selectGame = [[GameSelect alloc] initWithNibName:@"" bundle:nil];

Answer 3

制作如下，

- (IBAction)playButtonPressed:(UIButton *)sender 
{
    GameSelect *selectGame = [[GameSelect alloc] initWithNibName:@"GameSelect" bundle:nil];
    selectGame.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentModalViewController:selectGame animated:YES];
}

如果您的笔尖名称是任何其他名称而不是“GameSelect”，请给出“您的笔尖名称”。
